Playing a Cassette Tape

The tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. The longer side with the tape visible should face to the right. If you hear nothing or hear a garbled sound, the tape may not be in squarely. Press EJECT to remove the tape and start over.

If the ignition and radio are off, press the EJECT or RECALL buttons to insert and to begin play of a tape. If the ignition is on and the radio is off, the tape can be inserted and will begin playing.

While the tape is playing, use the VOLUME, SEEK, FADE, BAL, BASS, and TREB controls just as you do for the radio. The display will show an arrow to show which side of the tape is playing. The tape player will play the other side of the tape when it reaches the end.

Cassette tape adapter kits for portable CD players will work in your cassette tape player.

The tape bias is set automatically when a metal or chrome tape is inserted.

If an error appears on the display, see "Cassette Tape Messages" later in this section.

Cassette Tape Messages

E (Error): If this message and a number appears on the display, it could be for one of the following reasons:

    • E10: The tape is tight and the player cannot turn the tape hubs. Remove the tape. Hold the tape with the open end down and try to turn the right hub counterclockwise with a pencil. Turn the tape over and repeat. If the hubs do not turn easily, the tape may be damaged and should not be used in the player. Try a new tape to make sure the player is working properly.
    • E11: The tape is broken. Try a new tape.
CLN (Clean): If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but it should be cleaned as soon as possible to prevent damage to the tapes and player. See Care of the Cassette Tape Player . If the cassette tape is not playing correctly, for any other reason, try a known good cassette. If any error occurs repeatedly or if an error cannot be corrected, contact your GM dealer. If the radio displays an error number, write it down and provide it to your GM dealer when reporting the problem.

Playing a CD

Insert a CD partway into the slot, label side up. The player will pull it in and the CD should begin playing. If you want to insert a CD while the ignition or the radio off, first press the EJECT or the RECALL button.

If the ignition or radio is turned off with a CD in the player, it will stay in the player. When the ignition or radio is turned on, the CD will start playing where it stopped, if it was the last selected audio source.

When a CD is inserted, CD will appear on the display. As each new track starts to play, the track number will appear on the display.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

If playing a CD-R the sound quality may be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. There may be an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur try a known good CD.

Do not add paper labels to CDs, they could get caught in the CD player.

If an error appears on the display, see "CD Messages" later in this section.
